ActivePlastics - Preparation of PVC paste for test purpose - Planetary-mixer method
塑料 试验用聚氯乙烯（PVC）糊的制备 行星混合器法
Application Summary AI generated
This standard specifies the procedure for preparing PVC paste using a planetary mixer, ensuring consistent and reproducible test samples. It is applied in the plastics industry for quality control and material characterization of PVC plastisols, particularly in the production of coatings, sealants, and dipped goods. The method is used by manufacturers and testing laboratories to standardize paste preparation before evaluating properties like viscosity, gelation, and fusion behavior.
